I was just replacing the cam follower, and on pulling the pump out it got caught in the banjo pipe and twisted.
Basically the end of the piston has snapped off from the end of the spring.
Dont know if it was like it before as ive only had the car a week
what do i do? safe to put back together?
Appreciate the help
-
Any chance of a few pics so we are clear on the problem?

That is scrap now I am afraid. You either need a new piston or a whole new punp
-
Can you buy the piston/ spring from anywhere?
Isn't this the part that you upgrade for better fuel flow? So there must be loads lying around in peoples garage's
-
Yes that the part people upgrade so will be hundereds rolling around in people garages :happy2:

Don't fit a second hand piston into a pump. Buy a whole second hand pump

Don't fit a second hand piston into a pump. Buy a whole second hand pump
Why's that?

Probably because another piston will have different wear to the part that it fits into on yours? - and therefore won't work properly.
Sounds like pretty good advice to me - a lot of very knowledgeable people on here

It's the one with the top hat on it but doesn't come with the top hat

Buy a good used pump as already said.... Fitting a second hand piston is as bad as people buying a second hand rod/piston on eBay and just throwing it in to an engine. You're looking at £50-60 for a decent pump
-
Yeah I think I have a good used pump sorted
-
I bought a good second hand pump.
It was the newer version without banjo fixing and the pressure release valve.
The top sensor was cracked and been repaired, was told it still works but looks nasty.
No problem I'll just swap the top sensor over from my old pump along with the banjo fitting, but I can't get the top sensor to sit at 11 o'clock like it should...ends up at 1 o'clock every time, anyone know why?
Dies the sensor need to sit at that angle?
-
If refitting your engine cover then yes, you will need the sensor to sit at the right position
-
Yeah the engine cover will be going back on.
Anyone know why it won't tighten to 11 o'clock? Bizarre
-
Because its a part thats not available separately and is not designed to be swapped and changed between pumps?
-
I guess the threads are slightly different between old and new hpfp.
As when I put the newer sensor in the old pump it ends up at 1 o'clock
Old sensor in new pump ends up at 1 o'clock
Put them Both back in it's original pump and they end up at 11 o'clock.
??? Driving me mad....suppose I'll just use the damaged/repaired sensor
-
Oops
-
I've ordered a pressure release valve form vw as my pump didn't have one.
Hopefully pick it up and fit it all tomorrow. :stupid:

wondering why you didn't fit the complete replacement pump in?

just read what I missed, older one doesn't have a pressure release valve as it's an AXX engine code pump!!!
Who's sensor was repaired?, the used one :scared:

@r5gtt (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=11199)
My original pump has banjo and no pressure release valve.
The pump I bought has hose (no banjo) and a hole for a pressure release valve, and a cracked/repaired top sensor.
Hope that makes sense
-
So you brought a replacement pump with a broken sensor??
99% sure if you removed the 'bamboo' fitting on your replacement pump the bango bolt would have fit it the now vacant hole.
Ok just re read through. So basically you brought a pump with a broken sensor and are trying to replace the sensor from your original one with the snapped piston.

oh heck!!! I understand now but again why would you buy a pump with damaged sensor as you can get them for £50-60 in tact :sad1: would have given you my internal FOC just postage but you'd laughed it off as you bought one :doh:
-
Just to jump in here, if anyone is selling a second hand pump fire me a PM :)
My sensor snapped, I repaired it, was ok for a while but didn't last... EPC light on again, limp mode.
@OP: I wouldn't trust the snapped sensor repair mate, if it does go it's like hitting a wall from WOT to Limp Mode, better safe than sorry :happy2:
-
I should have one available in next day or so as I am having to replace due to the piston staring to crack. Sensor is fine if you wanted to rebuild yours with the parts
-
All done folks, drama over.
I'm going to get an intake next and get rid of the engine cover, then I can put my other sensor on top. If id of used it now i think the engine cover would of broke it due to the fact the it sits at the wrong angle when installed in the new hpfp
